In the real-time video display area 77, a black-and-white video to be diagnosed that visualizes the echo of the ultrasound is displayed. By updating the image of the diagnostic video 76 with an update cycle of 1/60 seconds, the image changes in real time in accordance with the movement of the diagnostic object in the real-time video display area 77. In other words, in the real-time video display area 77, it can be said that the image changes according to the movement of the diagnostic object at a predetermined frequency equal to or lower than the update period of 60 seconds. Note that the real-time video display area may include an area where the image does not change temporarily even when the diagnostic video 76 image is updated. Further, the image change in the real-time video display area 77 may not be periodic.

  The specific information display area 78 is a part of the diagnostic video 76 excluding the real-time video display area 77. The specific information display area 78 is arranged on the left side, the right side, and the lower side of the real-time video display area 77, for example. In other words, the specific information display area 78 is arranged outside the real-time video display area 77 with respect to the center position of the diagnostic video 76. Predetermined specific information is displayed in the specific information display area 78. In the specific information display area 78, for example, a diagnosis result list, a diagnosis method selection button, a setting condition input button, a diagnosis start button and an end button, a heart rate, a diagnosis date and time, and the like are displayed. In the present embodiment, by updating the image of the diagnostic video 76, the image of the region indicating the heart rate and the diagnosis date / time in the specific information display region 78 changes at a lower frequency than the update cycle of the diagnostic video 76. To do. For example, the image of the area indicating the diagnosis date / time changes at intervals of one second. The images in other areas do not change, and the frequency of changes seems to be extremely low. In other words, the frequency at which the image in the specific information display area 78 changes is lower than the frequency at which the image in the real-time video display area 77 changes as well as the diagnostic video 76. The layout of the real-time video display area 77 and the specific information display area 78 in the diagnostic video 76 is not limited to the example of FIG.

  The diagnostic images of the diagnostic apparatuses 71B, 71C, and 72A to 72C each include a real-time video display area and a specific information display area that are different from the diagnostic video 76 (not shown). In the present embodiment, each real-time video display area is arranged at a position that includes the approximate center position of each diagnostic video. The aspect ratio of each real tie video display area is different from the aspect ratio of the real time video display area 77. The aspect ratio is a ratio between the length in the X-axis direction and the length in the Y-axis direction of the image. Each specific information display area is arranged at least on either the right side or the left side of the diagnostic video. The specific information display area of each diagnostic apparatus has a different layout from the specific information display area 78. In the present embodiment, in each of the diagnostic apparatuses 71A to 71C and 72A to 72C, an area including at least a part of the real-time video display area is a change target area.

The program is stored in the flash ROM 32 when the HMD 1 is shipped. The flash ROM 32 stores a table 100 (see FIG. 12) described later. The RAM 33 temporarily stores various data. The first decoder 81 has an input terminal 91. The first decoder 81 is a video processing unit that decodes an analog video signal input via the input terminal 91.

<Display magnification change pattern storage processing>
The display magnification change pattern storage process executed by the CPU 31 of the CB 40 will be described with reference to FIG. The display magnification change pattern storage process is a process in which the CPU 31 stores the change target area desired by the user, the display magnification desired by the user, and the like in the flash ROM 32. The user connects one of the cables 71 and 72 to one of the input terminals 91 and 92. Any of the diagnostic devices 71 </ b> A to 71 </ b> C is connected to the cable 71. Any of the diagnostic devices 72 </ b> A to 72 </ b> C is connected to the cable 72. The user wears the HMD 1 to which the deflection unit 59 is attached and turns on the power of the HMD 1. Further, the user sets a mode in which the CPU 31 executes the display magnification change pattern via the operation unit 96. The CPU 31 starts processing based on the program stored in the flash ROM 32. Thereby, the display magnification change pattern storage process is executed. In the following description, a case where the diagnostic device 71A is connected to the input terminal 91 via the cable 71 and the diagnostic device 72A is connected to the input terminal 92 via the cable 72 will be described as an example.

  The CPU 31 determines whether a video signal is input (S11). The CPU 31 determines whether a video signal is input based on whether at least one of the first decoder 81 and the second decoder 82 receives the video signal. The CPU 31 stands by until a video signal is input (S11: NO). When the CPU 31 determines that a video signal is input (S11: YES), it determines whether a video signal is input to both the input terminals 91 and 92 (S13). The CPU 31 stands by until a video signal is input to only one of the input terminals 91 and 92 (S13: YES). For example, if the user removes the cable 72 connected to the diagnostic device 72 </ b> A from the input terminal 92, the video signal is input only to the input terminal 91. When the CPU 31 determines that the video signal is input to only one of the input terminals 91 and 92 (S13: NO), the CPU 31 specifies the input terminal to which the video signal is input (S15). The CPU 31 causes the selector 83 to select a decoder corresponding to the input terminal specified in S15 out of the first decoder 81 and the second decoder 82. The selector 83 selects and accepts the video signal decoded by the first decoder 81 as a specific video signal. The specific video signal received by the selector 83 is stored in the input buffer 84.

  The CPU 31 causes the image light generation unit 6 to display the specific video of the specific video signal selected by the selector 83 (S17). For example, the CPU 31 transmits a signal to the second image processing unit 102, the output control unit 86, and the connection I / F controller 87. Accordingly, the second image processing unit 102, the output control unit 86, and the connection I / F controller 87 execute the following processing. The second image processing unit 102 acquires a specific video signal stored in the input buffer 84 and performs mirror image inversion processing. The mirror image inversion process is achieved, for example, by rearranging the arrangement order of pixels in each row (that is, in the X-axis direction) for each frame indicated by the specific video signal. That is, the mirror image inversion process is performed in the horizontal direction of the image. The second image processing unit 102 outputs the specific video signal of the specific video that has undergone the mirror image inversion process to the output buffer 85. The output buffer 85 stores the specific video signal that is mirror-inverted and output from the second image processing unit 102. The output control unit 86 acquires the specific video signal stored in the output buffer 85 and outputs it to the connection I / F controller 87. The connection I / F controller 87 serially converts the specific video signal and then transmits it to the connection I / F controller 17 via the cable 7. The connection I / F controller 17 converts the serial-converted specific video signal into parallel and outputs it to the image light generation unit 6. The image light generator 6 generates image light of the diagnostic image 76 that is mirror-inverted and emits the image light to the half mirror 56. The user visually recognizes the diagnostic video 76 of the diagnostic apparatus 71A as the specific video via the half mirror 56.

  CPU31 acquires the characteristic pattern of the specific information display area 78 of the diagnostic image | video 76 (S19). The characteristic pattern of the specific information display area 78 is an image pattern of the specific information display area. When the CPU 31 transmits a signal to the first image processing unit 101, the first image processing unit 101 executes a process of acquiring the feature pattern of the specific information display region 78 at the upper right and upper left of the diagnostic video 76. For example, the first image processing unit 101 acquires pixel data of the diagnostic video 76 in order along the X-axis direction from a pixel at the upper left end of the diagnostic video 76 (hereinafter referred to as a first pixel). The first image processing unit 101 acquires the coordinates of points at which the sequentially acquired pixel data is discontinuous. The discontinuous point is a point where a difference in value between adjacent pixels is larger than a predetermined threshold, for example, when a white pixel changes to a black pixel. After that, the first image processing unit 101 acquires image data along the X-axis direction from the pixel one dot below the first pixel in the same manner as described above, and acquires the coordinates of discontinuous points. . As a result, the first image processing unit 101 acquires the feature pattern of the specific information display area 78 at the upper left of the diagnostic video 76. That is, the feature pattern is data in a predetermined format indicating a set of coordinate points where the pixel data is discontinuous. Similarly, the first image processing unit 101 acquires a feature pattern of the specific information display area 78 at the upper right of the diagnostic video 76. Note that the above-described processing performed by the first image processing unit 101 may be executed by the CPU 31 by executing a program stored in the flash ROM 32.

  The CPU 31 determines whether a change target area has been selected (S21). For example, the user selects an area including at least a part of the real-time video display area 77 in the diagnostic video 76 as a desired change target area via the operation unit 96. The aspect ratio of the change target area selected by the user via the operation unit 96 is set to be the same as the aspect ratio of the image light generated by the image light generation unit 6.

  The CPU 31 acquires the coordinates of the center position of the change target area and the magnification when the image light generation unit 6 displays the change target area (S23). The aspect ratio of the change target area selected by the user is the same as the aspect ratio of the image light displayed on the image light generation unit 6. Therefore, the magnification is obtained by dividing the diagonal distance of the image light of the image light generation unit 6 by the diagonal distance of the selected change target region. In the present embodiment, the diagonal distance of the change target region is half of the diagonal distance of the image light of the image light generation unit 6. For example, the CPU 31 acquires (500, 500) as the coordinates of the center position of the change target area and acquires 2 times as the magnification.

  The CPU 31 acquires the presence / absence of mirror image reversal and the luminance correction amount when the change target area is changed and displayed on the image light generated by the image light generation unit 6 (S25). For example, the user inputs the mirror image reversal on and the luminance correction amount 1 a via the operation unit 96 when changing the magnification of the region including at least a part of the real-time video display region 77 to be displayed on the image light generation unit 6. . The CPU 31 acquires the mirror image reversal ON and the luminance correction amount 1a.

  The CPU 31 displays the characteristic pattern of the specific information display area acquired in S19, the magnification acquired in S23 and the coordinates of the center position of the change target area, the presence / absence of mirror image inversion acquired in S25, and the luminance correction amount in the table 100 (see FIG. 12). (S27), and the display magnification change pattern storage process is terminated. The display magnification change pattern storage process is executed corresponding to each of the diagnostic apparatuses 71A to 71C and 72A to 72C. In the display magnification change pattern storage processing in each diagnostic device, the user operates the operation unit 96 to select an area including at least a part of the real-time video display area as a change target area, and whether or not mirror image inversion exists. Then, a desired luminance correction amount is input. The luminance correction amount is, for example, a coefficient of correction (for example, addition or multiplication) performed by the second image processing unit 102 on the value of each pixel of the image indicated by the specific video signal. Alternatively, the luminance correction amount may be information indicating a dynamic range that designates a pixel value in a range that can be displayed by the image light generation unit 6. As a result, display magnification change patterns for changing and displaying the respective real-time video display areas of the diagnostic apparatuses 71A to 71C and 72A to 72C are stored in the table 100.

<Table 100>
The table 100 will be described with reference to FIG. The table 100 stores input terminals, diagnostic device data, magnification setting data, and image processing data in association with each other. The data stored in the input terminal column is data stored when the HMD 1 is shipped, and the data stored in each column of the diagnostic device data, the magnification setting data, and the image correction processing data is the display magnification change pattern storage process. Is stored every time is executed. The input CH1 and input CH2 are stored in the input terminal column. The input CH1 is data indicating the input terminal 91, and the input CH2 is data indicating the input terminal 92.

  The diagnostic device data column is divided into a diagnostic device column and a feature pattern column. The data stored in the column of the diagnostic device is index data corresponding to each of the inputs CH1 and CH2, and each time the display magnification change pattern storage process (see FIG. 11) is executed, either the input CH1 or CH2 is stored. Are stored in order. For example, when the display devices 71A to 71C are sequentially connected to the input terminal 91 and the display magnification change pattern storage process is executed each time the connection is made, 71A to 71C are sequentially displayed in the column of the diagnosis device corresponding to the input CH1. Remembered. Similarly, when the diagnostic devices 72A to 72C are sequentially connected to the input terminal 92 and the display magnification change pattern storage process is executed each time the connection is made, 72A to 72C are sequentially displayed in the column of the diagnostic device corresponding to the input CH2. Remembered. In this embodiment, 71A-71C memorize | stored in the column of a diagnostic apparatus respectively shows diagnostic apparatus 71A-71C, 72A-72C shows diagnostic apparatus 72A-72C, respectively.

  In the feature pattern column, a feature pattern acquired by the CPU 31 executing S19 is stored corresponding to each data stored in the diagnostic device column. The feature patterns 71A to 71C stored in the feature pattern column respectively indicate the feature patterns of the specific information display area in the diagnosis devices 71A to 71C, and the feature patterns 72A to 72C respectively indicate the specific information display regions in the diagnosis devices 72A to 72C. The characteristic pattern of is shown. The diagnostic devices 71A to 71C and 72A to 72C are diagnostic devices of different models, and the characteristic patterns of the specific information display areas corresponding to the diagnostic devices are also different from each other.

  The column of magnification setting data is divided into a column of central coordinates and a column of magnification corresponding to each combination of data stored in the column of the diagnostic device. The center coordinate column stores the coordinates of the center position of the change target area selected by the user, which is acquired by the CPU 31 executing S23. In the magnification column, the magnification calculated by the CPU 31 executing S23 is stored corresponding to each of the data stored in the diagnostic device column. That is, the magnification setting data includes the coordinates of the center position of the change target area and the magnification. Hereinafter, of the magnification setting data, data corresponding to the input CH1 (input terminal 91) is referred to as first magnification setting data, and data corresponding to the input CH2 (input terminal 92) is referred to as second magnification setting data. In FIG. 12, as an example, three first magnification setting data are stored corresponding to the diagnostic devices 71A to 71C, respectively, and three second magnification setting data are respectively corresponding to the diagnostic devices 72A to 72C. Remembered. In other words, the flash ROM 32 stores three first magnification setting data and feature patterns 71A to 71C each corresponding to each of the three magnification setting data. Further, the flash ROM 32 stores three pieces of second magnification setting data and feature patterns 72A to 72C each corresponding to each of the three pieces of magnification setting data.

  The image processing data column is divided into a mirror image reversal column and a luminance correction amount column corresponding to each combination of data stored in the diagnostic device column. The mirror image reversal column stores data indicating whether the mirror image reversal on or the mirror image reversal off is performed on an area including at least a part of the real-time video display area that is the change target area. The data stored in the mirror image reversal column is acquired by the CPU 31 executing S25. The brightness correction amount column stores the brightness correction amount for correcting the brightness of the real-time video display area that is the change target area. The data stored in the luminance correction amount column is acquired by the CPU 31 executing S25. The brightness correction amount and the data stored in the mirror image inversion column are stored corresponding to the first magnification setting data and the second magnification setting data, respectively.

<Display processing>
Display processing executed by the CPU 31 of the CB 40 will be described with reference to FIG. After the display magnification change pattern storage process is executed, the user connects any of the diagnostic devices 71A to 71C and 72A to 72C to any of the cables 71 and 72. The user wears the HMD 1 and turns on the power of the HMD 1. Further, the user sets a mode in which the video of the input video signal is displayed on the HD 10 via the operation unit 96. The CPU 31 starts processing based on the program stored in the flash ROM 32. Thereby, the display process is executed. In the following description, an example in which the deflection unit 59 is attached to the HMD 1 will be described.

  The CPU 31 determines whether a video signal is input (S31). When the CPU 31 determines that no video signal is input (S31: NO), it displays a black screen on the image light generator 6 (S33). The CPU 31 transmits signals to the second image processing unit 102, the output control unit 86, and the connection I / F controller 87. The second image processing unit 102 generates a black screen video signal and outputs it to the output buffer 85. The description until the video signal of the black screen stored in the output buffer 85 is transmitted to the image light generation unit 6 overlaps with the description of S17, and will be omitted. Note that the CPU 31 may cause the image light generation unit 6 to display a white screen instead of the black screen.

  The CPU 31 determines whether an end instruction has been detected (S35). The CPU 31 stands by until an end instruction is input via the operation unit 96 (S35: NO). When the end instruction is input (S35: YES), the CPU 31 ends the display process.

  When CPU 31 detects the input of the video signal (S31: YES), CPU 31 determines whether the video terminal is input to both input terminals 91 and 92 (S37). When the CPU 31 determines that the video signal is input to only one of the input terminals 91 and 92 (S37: NO), the CPU 31 specifies the input terminal to which the video signal is input (S39) and performs processing. Proceed to S44. For example, when a video signal is input to the input terminal 91, the CPU 31 identifies the input terminal 91 as an input terminal to which the video signal is input.

  When the CPU 31 determines that the video signal is input to both the input terminals 91 and 92 (S37: YES), the CPU 31 refers to the priority information stored in the flash ROM 32. The priority information is information indicating an input terminal corresponding to a decoder that the selector 83 prioritizes selection when a video signal is input to both of the input terminals 91 and 92. At the time of shipment of the HMD 1, for example, input CH2 (input terminal 92) is stored as priority information. The CPU 31 determines the input terminal 92 as an input terminal for receiving a video signal (S43). Note that the input CH2 (input terminal 92) may be stored as priority information at the time of factory shipment.

  The CPU 31 selects, as a specific video signal, a video signal corresponding to the input terminal specified in S39 or the input terminal determined in S43 among the video signal input to the input terminal 91 and the video signal input to the input terminal 92. 83 is selected (S44). The selector 83 receives the selected video signal and outputs it to the input buffer 84. The input buffer 84 stores the input video signal. In the following description of the display process, a case will be described in which the selector 83 selects and accepts the diagnostic video 76 video signal input to the input terminal 91 as the specific video signal. The CPU 31 causes the selector 83 to select the first decoder 81 out of the first decoder 81 and the second decoder 82. The selector 83 selects and accepts the video signal of the diagnostic video 76 processed by the first decoder 81 as the specific video signal. The video signal of the diagnostic video 76 is stored in the input buffer 84.

  The CPU 31 determines whether the display magnification change mode is set (S45). The user can set either the normal display mode or the display magnification change mode via the operation unit 96. Information indicating the set mode is stored in the flash ROM 32 or the RAM 33. The normal display mode is a display mode in which a video corresponding to a video signal input to the HMD 1 is displayed on the image light generation unit 6 as it is. The display magnification change mode is a display mode in which a magnification change video is displayed.

  When the CPU 31 determines that the display magnification change mode is not set (S45: NO), the CPU 31 causes the image light generator 6 to display the specific video (S47). When the user sets the normal display mode, the CPU 31 determines that the display magnification change mode is not set (S45: NO). For example, the CPU 31 causes the image light generation unit 6 to display the diagnostic video 76 as the specific video. The description of how the CPU 31 displays the diagnostic video 76 on the image light generator 6 is omitted because it overlaps with S17.

  The CPU 31 determines whether an end instruction has been input (S49). The CPU 31 stands by until an end instruction is input via the operation unit 96 (S49: NO). If the CPU 31 determines that an end instruction has been input (S49: YES), it advances the process to S63. The CPU 31 updates the priority information stored in the flash ROM 32 to the information of the input terminal to which the specific video signal selected by the selector 83 in S44 has been input (S63), and ends the display process.

  On the other hand, when determining that the display magnification change mode has been set (S45: YES), the CPU 31 executes a display magnification change pattern determination process (S51). The display magnification change pattern determination process executed by the CPU 31 will be described with reference to FIG. The CPU 31 refers to the flash ROM 32 and acquires the table 100 (S71). CPU31 acquires the characteristic pattern of the specific information display area in the specific video of the specific video signal (S73). The manner in which the CPU 31 acquires the feature pattern is the same as that in S19, and thus the description thereof is omitted. For example, when the video signal of the diagnostic video 76 is input to the input terminal 91, the CPU 31 transmits a signal to the first image processing unit 101, so that the first image processing unit 101 displays the specific information of the diagnostic video 76. Processing for acquiring the feature pattern of the region 78 is executed. In this case, since the diagnostic device 71A is connected to the input terminal 91, the feature pattern acquired by the first image processing unit 101 is the same as the feature pattern 71A stored in the table 100.

  The CPU 31 determines whether a feature pattern that matches the feature pattern acquired in S73 is stored in the table 100 corresponding to the input terminal to which the specific video signal selected in S44 is input (S75). For example, the CPU 31 determines whether or not a feature pattern that matches the feature pattern in the specific information display area 78 acquired in S73 is stored corresponding to the input CH1 of the table 100. For example, the CPU 31 stores data in a predetermined format (hereinafter referred to as first data) indicating a set of coordinate points at which the pixel data of the specific information display area 78 is discontinuous, and stored in correspondence with the input CH1. Comparison is sequentially made with any of -71C. Then, the CPU 31 determines whether any one of the feature patterns 71A to 71C is completely coincident with the first data or data corresponding to a partial region is coincident (partial coincidence). If the CPU 31 determines that no matching feature pattern is stored (S75: NO), it stores Flag = 1 in the flash ROM 32 (S77), and returns the process to the display process.

  If the CPU 31 determines that a matching feature pattern is stored (S75: YES), it stores Flag = 0 in the flash ROM 32 (S79), and advances the process to S81. The CPU 31 acquires predetermined magnification setting data and predetermined image processing data corresponding to the feature pattern acquired in S73 from specific magnification setting data (described later) (S81), and returns the processing to the display processing. Among the three first magnification setting data and the three second magnification setting data stored in the table 100, the specific magnification setting data includes three corresponding to the input terminal to which the specific video signal selected by the CPU 31 in S44 is input. This is the magnification setting data. For example, when the CPU 31 causes the selector 83 to select the video signal of the diagnostic video 76 input to the input terminal 91 as the specific video signal (S44), the three first magnifications corresponding to the input CH1 (input terminal 91) The setting data becomes specific magnification setting data. The CPU 31 acquires the center coordinates (500, 500) and the magnification 2 as the predetermined magnification setting data corresponding to the feature pattern 71A from the three first magnification setting data that are the specific magnification setting data, and further, the predetermined image. Mirror image inversion ON and luminance correction amount 1a are acquired as processing data.

  As shown in FIG. 13, the CPU 31 refers to the flash ROM 32 and determines whether Flag = 1 (S53). If the CPU 31 determines that Flag = 1 (S53: YES), it causes the image light generator 6 to generate the image light of the error message (S55), and proceeds to S33. The CPU 31 causes the image light generator 6 to display, for example, “No display pattern corresponding to the diagnostic device is stored” as an error message (S55), and display a black screen after a predetermined time. (S33).

  When the CPU 31 determines that Flag = 1 is not satisfied (S53: NO), the CPU 31 generates a magnification change video signal (S57). The CPU 31 transmits a signal to the first image processing unit 101 and the second image processing unit 102. Thereby, the first image processing unit 101 and the second image processing unit 102 execute the following processing. The first image processing unit 101 acquires the specific video signal stored in the input buffer 84, and specifies the change target area according to the predetermined magnification setting data acquired by the CPU 31 in S81. The second image processing unit 102 acquires the specific video signal stored in the input buffer 84, and displays the display target area specified by the first image processing unit 101 according to the predetermined magnification setting data acquired by the CPU 31 in S81. A process for changing the display magnification is executed, and the image is processed according to predetermined image processing data. Thereby, the second image processing unit 102 generates a video signal of a video whose display magnification is changed. The magnification change video signal generated by the second image processing unit 102 is stored in the output buffer 85. For example, the first image processing unit 101 specifies an area including at least a part of the real-time video display area 77 as the change target area, and the second image processing unit 102 specifies the area specified by the first image processing unit 101. A magnification-change video signal is generated by enlarging at a magnification of 2, inversion of the mirror image, and performing luminance correction of the luminance correction amount 1a. Note that the processing executed by the first image processing unit 101 and the second image processing unit 102 may be executed by the CPU 31 by executing a program stored in the flash ROM 32.

  The CPU 31 displays the image of the magnification change video signal generated in S57 on the image light generation unit 6 (S59). The CPU 31 transmits a signal to the output control unit 86 and the connection I / F controller 87. The output control unit 86 acquires the magnification change video signal stored in the output buffer 85 and outputs it to the connection I / F controller 87. The connection I / F controller 87 outputs the magnification change video signal to the connection I / F controller 17 via the cable 7. The connection I / F controller 17 acquires the magnification change video signal transmitted via the cable 7 and outputs it to the image light generation unit 6. The image light generation unit 6 generates image light of the change target region that is mirror-inverted and enlarged at a magnification of 2 based on the input magnification change video signal.

  The image light generation unit 6 emits the generated image light toward the left side of the half mirror 56. The half mirror 56 reflects the transmitted image light in the backward direction that is a direction intersecting the left direction. The user visually recognizes the area to be changed, which is not mirror-inverted and enlarged, through the half mirror 56 as a magnification change image. That is, the user visually recognizes an image in which at least a part of the real-time image display area 77 is enlarged. The user can make a desired diagnosis while visually recognizing the video in a hands-free state.

  The CPU 31 determines whether an end instruction has been input (S61). The CPU 31 stands by until an end instruction is input via the operation unit 96 (S61: NO). If the CPU 31 determines that an end instruction has been input (S61: YES), it executes S63 and ends the display process.

  Next, a case where a diagnostic device 72A instead of the diagnostic device 71A is connected to the input terminal 92 via the cable 72 and display processing is executed will be described. Similar to the above, the processing of S31 to S43 is executed. The CPU 31 causes the selector 83 to select the video signal of the diagnostic device 72A input to the input terminal 92 as a specific video signal (S44). When the user selects the display magnification change mode via the operation unit 96 (S45: YES), S51 and S71 to S79 are executed as described above. The CPU 31 acquires center coordinates (400, 500) and a magnification of 2.5 as predetermined magnification setting data corresponding to the feature pattern 72A from the three second magnification setting data that are specific magnification setting data (see FIG. 12). In addition, mirror image inversion ON and luminance correction amount 2a are acquired as image processing data (S81). The second image processing unit 102 that has received the signal from the CPU 31 generates a magnification-change video signal obtained by enlarging the real-time video display area of the diagnostic device 72A (S57). The user can visually recognize the magnification change video through the half mirror 56. The CPU 31 updates the priority information to the information of the input terminal 92 (S63), and ends the display process.

  Next, instead of the diagnostic device 72A, a case where the diagnostic device 71B is connected to the input terminal 91 via the cable 71 and display processing is executed will be described. Similar to the above, the processing of S31 to S79 is executed. The CPU 31 acquires center coordinates (550, 450) and a magnification of 1.5 as predetermined magnification setting data corresponding to the feature pattern 71B from the three first magnification setting data which are specific magnification setting data (see FIG. 12). Further, mirror image inversion off and luminance correction amount 1b are acquired as image processing data (S81). The second image processing unit 102 that has received the signal from the CPU 31 generates a magnification-change video signal in which an area including at least a part of the real-time video display area of the diagnostic apparatus 71B is enlarged without mirror image reversal (S57). The image light generation unit 6 generates a change target region that is not mirror-inverted and enlarged at a magnification of 1.5 as a magnification-change video. The user removes the deflection unit 59 including the half mirror 56 from the housing 12 (see FIG. 7), and can directly view the image light generated by the image light generation unit 6 through the opening portions 121 and 122.

<Main functions and effects of this embodiment>
As described above, the CPU 31 stores the first magnification setting data and the second magnification setting data corresponding to the input terminals 91 and 92 (inputs CH1 and CH2) by executing the display magnification change pattern storage process ( S11 to S27). Thus, the magnification setting data desired by the user is stored in correspondence with each of the diagnostic devices 71A to 71C and 72A to 72C input to the input terminals 91 and 92. When the image light generator 6 displays the magnification-changed video, when a video signal is input to at least one of the input terminals 91 and 92, the CPU 31 causes the selector 83 to change One of the first decoder 81 and the second decoder 82 is selected (S39, S43). The CPU 31 selects a video signal input to one of the input terminals 91 and 92 as a specific signal. The CPU 31 causes the second image processing unit 102 to generate a magnification change video signal in accordance with predetermined magnification setting data included in the specific magnification setting data (S57). Thereby, the image light generation unit 6 can display the magnification change video desired by the user.

  If the magnification change display pattern desired by the user is stored in the flash ROM 32 by executing the display magnification change pattern storage process, the HMD 1 can be operated by the user for each of the diagnostic devices 71A to 71C and 72A to 72C. The selected change target area including at least a part of the real-time video display area is automatically displayed with the display magnification changed according to the first magnification setting data or the second magnification setting data. Each time the user alternately uses any of the diagnostic devices 71A to 71C connected to the input terminal 91 and any of the diagnostic devices 72A to 72C connected to the input terminal 92, the user selects the change target region and sets the display magnification. There is no need to input settings to the HMD 1. Therefore, the HMD 1 can display the display target area of the video signal input to each of the input terminals 91 and 92 by changing the display magnification corresponding to the input terminals 91 and 92 without designating the user. .

  In the display magnification change pattern storage processing, the user inputs data indicating whether the display target area is mirror-inverted. Thus, the CPU 31 stores the first magnification setting data and the second magnification setting data in the table 100 in association with data indicating whether the display target area is mirror-inverted (S27). The CPU 31 causes the second image processing unit 102 to generate either a magnification-change video signal that is mirror-inverted or a magnification-change video signal that is not mirror-inverted (S57). When the image light generation unit 6 generates image light with a mirror image inverted, the user visually recognizes the image light through the half mirror 56. On the other hand, when the image light generation unit 6 generates image light that is not mirror-inverted, the user directly visually recognizes the image light through the opening units 121 and 122. That is, the HMD 1 is in any case where the image light of the image displayed by the image light generation unit 6 is viewed through the half mirror 56 or directly through the half mirror 56. A magnification change video signal can be generated. Therefore, the usage method of HMD1 is diversified.

  The deflection unit 59 including the half mirror 56 is detachable from the housing 12. When the image light generation unit 6 generates image light that is mirror-inverted, the user can visually recognize the image light that is not mirror-inverted by attaching the deflection unit 59 to the housing 12. When the image light generator 6 generates image light that is not mirror-inverted, the user can visually recognize the image light that is not mirror-inverted by removing the deflection unit 59 from the housing 12. Depending on whether the image light generated by the image light generation unit 6 is mirror-inverted, the use of the image light through the half mirror 56 and the use of the image light directly through the half mirror 56 are properly used. Is possible. Therefore, the HMD 1 can appropriately allow the user to visually recognize the magnification-changed video as a video that is not mirror-inverted according to each application.

  The magnification change video signal is generated by the first decoder 81, the second decoder 82, the selector 83, the input buffer 84, the first image processing unit 101, the second image processing unit 102, and the output buffer 85 built in the housing 63. Is done. The generated magnification change video signal is transmitted to the HD 10 configured separately from the housing 63 via the connection I / F controller 87 provided in the housing 63. The HD 10 can display the magnification-change video only by including the connection I / F controller 17 and the image light generation unit 6. Thus, the HMD 1 can simplify the mechanism of the HD 10 configured separately from the CB 40.

  The CPU 31 displays the magnification-changed image whose luminance has been corrected in accordance with the luminance correction amount associated with the first magnification setting data and the second magnification setting data (S57 to S59). The user can visually recognize the image light whose luminance has been corrected. Therefore, the HMD 1 can easily make the user visually recognize the image light generated by the image light generation unit 6 according to the diagnostic devices 71A to 71C and 72A to 72C connected to any of the input terminals 91 and 92.

  Since the table 100 stores three pieces of first magnification setting data corresponding to the diagnostic devices 71A to 71C, the CPU 31 stores in the second image processing unit 102 the diagnostic devices 71A to 71C connected to the input terminal 91. A corresponding magnification change video signal can be generated (S57). Similarly, the CPU 31 can cause the second image processing unit 102 to generate a magnification change video signal corresponding to the diagnostic devices 72A to 72C connected to the input terminal 92 (S57). Therefore, the HMD 1 can display the magnification change video according to the diagnostic devices 71A to 71C and 72A to 72C connected to the input terminals 91 and 92, respectively. Even when a plurality of diagnostic devices are sequentially connected to the input terminals 91 and 92, the HMD 1 can display a magnification change image according to each diagnostic device.

  The diagnostic devices 71A to 71C and 72A to 72C connected to any one of the input terminals 91 and 92 are diagnostic devices of different models, and feature patterns of the specific information display areas are different from each other. By executing the display magnification change pattern storage process, the table 100 stores any one of the feature patterns 71A to 71C corresponding to each of the three first magnification setting data, and the three second magnification setting data. One of the feature patterns 72A to 72C is stored corresponding to each of the above. The CPU 31 acquires predetermined magnification setting data included in the specific magnification setting data among the three first magnification setting data and the three second magnification setting data based on the feature pattern identified in S73 (S81). , HMD1 does not receive an instruction from the user even when one diagnostic device is sequentially connected to any of input terminals 91 and 92, and appropriate magnification setting data according to the connected diagnostic device. And a magnification change image corresponding to each diagnostic apparatus can be displayed by appropriately changing the display magnification.

  In the feature pattern column of the table 100, feature patterns of the specific information display areas of the diagnostic apparatuses 71A to 71C and 72A to 72C are stored. Since the diagnostic devices 71A to 71C and 72A to 72C are diagnostic devices of different models, the characteristic patterns of the specific information display areas are different from each other. The CPU 31 can identify the diagnostic device connected to the input terminals 91 and 92 by causing the first image processing unit 101 to acquire the characteristic pattern of the specific information display area in the specific video (S73). . Therefore, the HMD 1 has a magnification change video signal after the video signal is input to any of the input terminals 91 and 92, as compared with the case where the feature pattern is extracted from each of the real-time video display area and the specific information display area of the specific video. It is possible to reduce the time until the is generated.

  The user visually recognizes the specific video through the half mirror 56 when the display magnification change pattern storage process is executed. In this case, since the real-time video display areas of the diagnostic apparatuses 71A to 71C and 72A to 72C are arranged at positions including the center position of the diagnostic video, the user can easily visually recognize the real-time video display area as a display target area.

<Modification>
In addition, this invention is not limited to the said embodiment, A various change is possible. The table 100 may not have a mirror image reversal column. That is, the table 100 may not store data indicating whether the real-time video display area is mirror-inverted. In this case, when generating the magnification change video signal, the HMD 1 may automatically generate a magnification change video signal in which the change target area is automatically mirror-inverted. The half mirror 56 is not detachable from the housing 12 but may be fixed.

  The table 100 does not have to be provided with a luminance correction amount column. That is, the table 100 may not store the luminance correction amount for correcting the luminance of the display target area. In this case, the CB 40 generates a magnification change video signal that does not perform luminance correction.

  The table 100 does not have to store the three first magnification setting data and the three magnification setting data. It is sufficient that at least one first magnification setting data and second magnification setting data corresponding to the diagnostic device connected to any one of the input terminals 91 and 92 is stored in the table 100.

  The table 100 may not have a feature pattern column. That is, the table 100 may not store feature patterns corresponding to the three first magnification setting data and the three second magnification setting data. In this case, instead of acquiring the feature pattern of the specific video and determining whether the matching feature pattern is stored in the table 100, the CPU 31 receives an instruction to select predetermined magnification setting data via the operation unit 96. That's fine. The user operates the operation unit 96 to select desired magnification setting data.

  The real-time video display area 77 may be arranged at a position that does not include the center position of the diagnostic video 76. In this case, the specific information display area 78 may be arranged at the center of the diagnostic video 76. CPU31 should just acquire the characteristic pattern of the center part of a diagnostic image | video, when performing S19 and S73.

  The aspect ratio of the display target area selected by the user in the display magnification change pattern storage process may not be the same as the aspect ratio of the image light generated by the image light generation unit 6. In this case, the length of the image light generated by the image light generation unit 6 in the X-axis direction is divided by the length of the display target region in the X-axis direction, or Y of the image light generated by the image light generation unit 6 The magnification is acquired by dividing the length in the axial direction by the length in the Y-axis direction of the display target area.

  The display target area may not be the real-time video display area of the diagnostic apparatuses 71A to 71C and 72A to 72C. The display target area may be, for example, specific information display areas of the diagnostic devices 71A to 71C and 72A to 72C.

  In the CB 40, instead of the first decoder 81 and the second decoder 82, a single image processing IC may be mounted on a substrate built in the housing 63. In addition, the CB 40 does not include the first decoder 81 and the second decoder 82, and executes processing corresponding to the functions of the first decoder 81 and the second decoder 82 by an operation performed by the CPU 31 in cooperation with the RAM 33. Also good.

   The input buffer 84, the first image processing unit 101, the second image processing unit 102, the output buffer 85, and the output control unit 86 are mounted as a single ASIC on the board built in the housing 63, It may be implemented as an individual IC. Further, the CB 40 may not include the input buffer 84, the first image processing unit 101, the second image processing unit 102, the output buffer 85, and the output control unit 86. In this case, processing corresponding to the functions of the input buffer 84, the first image processing unit 101, the second image processing unit 102, the output buffer 85, and the output control unit 86 is performed by an operation performed by the CPU 31 in cooperation with the RAM 33. May be executed.

   The magnification need not be greater than 1. The magnification may be 1 or smaller than 1. When the magnification is smaller than 1, the image light generation unit 6 generates image light in which the change target area is reduced.
